Syslog from faillure to next reboot

Hello,

Something really bizarre happened with firefox. It seems the kernel stopped to serve filesystem request because a hung process.

I ran de mozilla demo bananabread, exited one level and entered another and everything stopped to work. I tried to kill the process but it has a "D" on the status and cannot be killed.

After a while everything stopped to work. Even the reboot didn't work. I had to unplug the machine.

Kernel logs (syslog) is attached.

It seems something was failing in the disk. It has everything there until next reboot.

I don't know if it's a bug or not but wanted to make sure that nothing can be done.

I did an error installing bios raid. I have to undo it but I'm a little bit afraid of undoing without a backup.

root@red1:/var/log# dmraid -r
/dev/sdb: pdc, "pdc_bbbgggjccd", mirror, ok, 625011328 sectors, data@ 0
/dev/sda: pdc, "pdc_bbbgggjccd", mirror, ok, 625011328 sectors, data@ 0

This raid is getting me into troubles. Disk sdb is what failed.

--- Comment #1 from Theodore Tso <[email protected]> 2012-12-18 14:57:17 --- The kernel syslog shows a huge number of hard drive errors. So it looks like the problem is caused by a hardware failure. It is most likely a failing hard drive, but it's possible that the problem could be caused by a loose HDD cable.
